Description

Technical Field

[0001] The invention relates to the technical field of coke oven vehicle position detection, in particular to a coke oven reading head with a temperature compensation function. Background Art

[0050] The following will be combined with the specific embodiments of the present invention to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] Coke ovens are important industrial furnaces in the metallurgical industry, primarily used to refine coal into coke. Once coal is loaded into the coke oven's carbonization chamber, it undergoes high-temperature heating in two combustion chambers, sealed off from air. The process involves drying, pyrolysis, melting, solidification, and shrinkage, ultimately forming porous coke.

[0052] Coke oven vehicles are essential components of a coke oven, including coal loading cars, pushers, interceptors, and quenchers. Coal loading cars are primarily used to deliver coal to the oven. Pushers propel the oven, already loaded and undergoing the coking process, forward, pushing the coke out of the carbonization chamber. During the pushing process, interceptors guide the coke to the quencher, preventing it from spilling and removing it from the oven. Quenching cars receive the hot coke pushed out of the carbonization chamber and transport it to the quenching tower for quenching, after which the quenched coke is removed.

[0053] With the development of technology, "one-click coking" and 5G technologies are beginning to be applied to coke oven vehicles, enabling the automated operation of coke oven vehicles and the entire coke oven system. The automatic positioning technology for coke oven vehicles is achieved through the cooperation of a reading head and a coding plate. The reading head is installed on the coke oven vehicle, and the coding plate is installed at the corresponding position of the coke oven. The reading head recognizes the coding plate to confirm whether the coke oven vehicle is in place.

[0054] Unlike other fields in the prior art, the temperature of the coke oven system during operation is relatively high. The high temperature environment will cause the wavelength of the light waves emitted by the optical sensor to drift, resulting in a certain deviation in the measurement results of the reading head.

[0055] A coke oven reading head with a temperature compensation function of the present invention includes a shell 1, a mounting frame 2, a laser emitter 3, a positioning pin 4, a spring 5, a movable frame 6 and a fixed knob 7. The reading head is installed on a coke oven vehicle. By adjusting the position of the laser emitter 3, the detection deviation of the reading head caused by the high temperature environment can be compensated, thereby accurately detecting whether the position of the coke oven vehicle is in place.

[0056] After the laser emitted by the laser transmitter 3 is irradiated onto the coding plate, the different reflective properties of the coding plate surface are used to form reflected light of varying strengths. After receiving the reflected light, the photosensitive receiving device in the reading head converts it into an electrical signal. The intensity of these electrical signals corresponds to the intensity of the reflected light. By amplifying, filtering, shaping, and other operations on the electrical signals, the electrical signals are converted into digital or analog signals for further decoding and processing, thereby determining the position of the coke oven vehicle.

[0057] The laser emitter 3 is fixedly arranged in the mounting frame 2, and the mounting frame 2 is arranged at intervals in the shell 1. A positioning groove 201 is provided at the end of the mounting frame 2, and a positioning pin 4 is fixedly arranged at the end of the shell 1. A spring 5 is set to support the end of the mounting frame 2; by using the spring 5 to support the mounting frame 2, the positioning pin 4 can be engaged with the positioning groove 201 to achieve the fixation of the mounting frame 2 and the laser emitter 3, and the relative position of the positioning pin 4 and the shell 1 is adjustable. By adjusting the installation position of the positioning pin 4, the laser emitter 3 can be adjusted, thereby compensating for the detection deviation of the reading head.

[0058] There are two ambient temperatures when the coke oven vehicle is running, one is the normal temperature environment during transportation, and the other is the high temperature environment when close to the coke oven. Therefore, positioning grooves 201 are opened at both ends of the mounting frame 2, and the positioning pins 4 and springs 5 ​​are set to two. The two positioning pins 4 are fixedly set at the two ends of the outer shell 1, and the positions of the two positioning pins 4 correspond to the two ambient temperatures of the coke oven vehicle respectively. The two springs 5 ​​are respectively set at the two ends of the mounting frame 2, and the movable frame 6 is slidably set on the outer shell 1, and its two ends are respectively against the ends of the two springs 5 ​​away from the mounting frame 2.

[0059] like Figure 2 As shown, assuming that the right end of the shell 1 is the first end, when the right positioning groove 201 is engaged with the right positioning pin 4, the reading head is applied to the normal temperature environment conditions during the transportation of the coke oven vehicle; when the left positioning groove 201 is engaged with the left positioning pin 4, the reading head is applied to the high temperature environment conditions when the coke oven vehicle is close to the coke oven.

[0060] When the coke oven vehicle is in the process of transportation, the movable frame 6 is slid in the direction close to the first end. At this time, the elastic force of the spring 5 away from the first end is greater than the elastic force of the spring 5 close to the first end, thereby pushing the mounting frame 2 to move to the right, so that the positioning groove 201 close to the first end is engaged with the positioning pin 4 close to the first end; and when the coke oven vehicle runs to a position close to the coke oven, such as Figure 3 As shown, the movable frame 6 is slid in the direction away from the first end. At this time, the elastic force of the spring 5 away from the first end is less than the elastic force of the spring 5 close to the first end, thereby pushing the mounting frame 2 to move to the left, so that the positioning groove 201 away from the first end is engaged with the positioning pin 4 away from the first end, thereby realizing rapid switching of the laser emitter 3 between the two working conditions, and ensuring the accuracy of the detection results of the reading head.

[0061] like Figure 2 and Figure 3 As shown, the fixed knob 7 is connected to the movable frame 6 by threaded fitting and is abutted against the outer shell 1. When the fixed knob 7 is rotated to move it away from the outer shell 1, the movable frame 6 can be slid, and when the fixed knob 7 is rotated to abut against the outer shell 1, the movable frame 6 can be fixed to adjust and lock the movable frame 6. Of course, in order to improve the automation of the position adjustment of the laser emitter 3, the fixed knob 7 can be omitted, and the movable frame 6 can be directly connected to the output end of the telescopic equipment such as the cylinder and the electric cylinder.

[0062] The mounting frame 2 includes a frame body 21, a fixing device 22 and two limiting rings 23. Figure 3 and Figure 11 As shown, the frame 21 is arranged at intervals in the shell 1, the positioning grooves 201 are arranged at both ends of the frame 21, a spherical installation cavity 202 is provided in the frame 21, the fixture 22 is spherical, the fixture 22 is fixedly arranged in the installation cavity 202, and the laser emitter 3 is fixedly arranged in the fixture 22; the position of the fixture 22 in the installation cavity 202 can be adjusted, such as making the fixture 22 with a material such as rubber with greater friction. When a greater rotational force is applied to the fixture 22, the fixture 22 can be rotated, thereby adjusting the installation angle of the laser emitter 3.

[0063] Two limiting rings 23 are fixedly arranged at both ends of the frame 21. Figure 12 As shown, one end of the spring 5 is clamped in the limiting ring 23, thereby avoiding the risk of the spring 5 falling during use and ensuring the normal use of the reading head.

[0064] like Figure 2 and Figure 3 As shown, the axis of the limiting ring 23 coincides with the axis of the positioning groove 201 , so that the spring 5 can apply a uniform and stable force to the frame 21 , thereby preventing the frame 21 from deflecting.

[0065] In order to improve the connection stability between the positioning pin 4 and the mounting frame 2, it is preferred to allow multiple surfaces on the positioning pin 4 to cooperate with the mounting frame 2; Figure 5 As shown, a protruding structure is provided at one end of the positioning pin 4, the outer diameter of the protruding structure is smaller than the outer diameter of the end portion of the positioning pin 4, the peripheral side of the protruding structure is a conical surface 401, and the end face of the positioning pin 4 is a plane 402. The conical surface 401 and the plane 402 are continuously provided, and the conical surface 401 is in contact with the inner wall of the positioning groove 201, and the plane 402 is in contact with the mounting frame 2, thereby improving the fixing reliability of the mounting frame 2.

[0066] In order to prevent the mounting frame 2 from rotating around the axis of the positioning groove 201 during operation, it is preferred that the protruding structure at the end of the positioning pin 4 and the positioning groove 201 are both configured to be pyramidal or prism-shaped; it is preferred that the protruding structure and the positioning groove 201 are both configured to be quadrangular pyramidal, that is, the conical surface 401 is also quadrangular pyramidal.

[0067] The housing 1 is provided with a movable hole 101. The positioning pin 4 includes a pin body 41 and two rotating parts 42. The pin body 41 is arranged in the movable hole 101. The inner diameter of the movable hole 101 is larger than the outer diameter of the pin body 41, such as an oblong or elliptical shape. The two rotating parts 42 are connected to the pin body 41 through threaded fittings and are respectively arranged on the inner and outer sides of the housing 1. Figure 5 As shown, when the right rotating part 42 is rotated to move to the right, the pin body 41 can be moved to adjust the position of the pin body 41. When the pin body 41 moves to the specified position, the right rotating part 42 is rotated again to make it abut against the shell 1, so that the pin body 41 can be fixed to achieve two-dimensional movement of the pin body 41 and the laser emitter 3.

[0068] like Figure 5 As shown, when the right rotating member 42 is rotated to move rightward, the pin body 41 can also be rotated to adjust the pitch angle of the laser emitter 3.

[0069] like Figure 5 As shown, when the two rotating parts 42 are rotated in the same direction, or when the two rotating parts 42 are kept stationary and the pin body 41 is rotated, the pin body 41 can be moved along its axis. In conjunction with the above-mentioned movement operation, the pin body 41 and the laser emitter 3 can be adjusted in all directions, and the laser emitter 3 can be adjusted to different required positions.

[0070] like Figure 5 As shown, the left rotating member 42 is located inside the housing 1, so it is inconvenient to rotate. At the same time, since the left rotating member 42 is inconvenient to be fixed, when the pin body 41 is rotated, the left rotating member 42 will also be driven to rotate, affecting the adjustment efficiency of the pin body 41. In order to solve this problem, as Figure 11 and Figure 12As shown, a clamping block is provided on the rotating member 42, so that the clamping block extends into the movable hole 101 and is engaged with the movable hole 101. By utilizing this engaging fit, the rotating member 42 is prevented from rotating along with the pin body 41, thereby improving the operational convenience of the pin body 41.

[0071] Specifically, the pin body 41 includes an outer tube 411, a clamping joint 412, a sliding rod 413, a screw head 414 and a supporting plate 415. Figure 4 As shown, the outer tube 411 is connected to the rotating member 42 through threaded engagement, and the clamping joint 412 is fixedly disposed at one end of the outer tube 411 and is clamped to the positioning groove 201 .

[0072] like Figures 6-10 As shown, a sliding hole with a cross-shaped cross section is opened in the outer tube 411, and the sliding hole passes through the end of the card joint 412 away from the outer tube 411, and a sliding rod 413 is slidably set in the sliding hole, so that the sliding rod 413 is slidably set in the outer tube 411, and the screw head 414 is rotated and set at the end of the sliding rod 413 away from the card joint 412, and the screw head 414 is connected to the outer tube 411 through threaded engagement, and the supporting plate 415 is fixed on the sliding rod 413; the conical surface 401 is the peripheral side of the card joint 412, and the flat surface 402 is the side of the supporting plate 415 away from the sliding rod 413.

[0073] like Figure 3 and Figure 5 As shown, when the clamping joint 412 is clamped with the positioning groove 201 , the abutting plate 415 can abut the mounting bracket 2 , thereby improving the connection stability between the two.

[0074] like Figure 5 As shown, the right positioning pin 4 is engaged with the mounting frame 2, as shown in FIG. Figure 4 As shown, the left clamping joint 412 is spaced apart from the mounting bracket 2, and the left end of the mounting bracket 2 is fixed by the elastic force of the spring 5. When the coke oven vehicle is subjected to a large vibration, the spring 5 can be used to buffer the laser emitter 3, thereby improving the firmness of the fixation of the laser emitter 3 and avoiding the problem of damage to the mounting bracket 2 due to excessive force.

[0075] However, the buffering effect of the spring 5 will have a certain impact on the detection results of the reading head. In some scenarios with extremely high detection accuracy requirements, the laser emitter 3 needs to be rigidly connected to the shell 1. At this time, the screw head 414 is rotated without rotating the outer tube 411. The threaded combination of the screw head 414 and the outer tube 411 is used to drive the slide rod 413 and the supporting plate 415 to move to the right, so that the supporting plate 415 can be pressed against the left side of the mounting bracket 2, so that the mounting bracket 2 is rigidly connected to the shell 1; since the position of the outer tube 411 remains unchanged, when the mounting bracket 2 needs to be engaged with the positioning pin 4 on the left, the screw head 414 is rotated in the opposite direction so that the supporting plate 415 can be pressed against the right end of the outer tube 411, and the supporting plate 415 can be reset.

[0076] like Figure 9 As shown, a blind hole is provided at one end of the outer tube 411 away from the clamping joint 412, and an inner thread is provided on the inner wall of the blind hole. When the supporting plate 415 is away from the outer tube 411, the screw head 414 is connected with the inner thread through threaded engagement, as shown in FIG. Figure 11 As shown, when the supporting plate 415 is pressed against the end of the outer tube 411, the screw head 414 is just out of the blind hole, so that when the screw head 414 is rotated, the supporting plate 415 will not squeeze the end of the outer tube 411, which has a certain protective effect.

[0077] The above embodiment is for switching between two environmental working conditions. It is also possible to realize switching between multiple environmental working conditions by providing multiple movable frames 6, multiple positioning pins 4 and multiple positioning slots 201, thereby improving the working condition adaptability of the reading head.

[0078] The method of using the coke oven reading head with temperature compensation function of the present invention is as follows:

[0079] First, adjust the positions of the two locating pins 4 so that when the locating slot 201 engages the left locating pin 4, the laser emitter 3 is in the normal temperature installation position, and when the locating slot 201 engages the right locating pin 4, the laser emitter 3 is in the high temperature installation position. Then, adjust the position of the movable frame 6 to switch the laser emitter 3 to the desired operating position. The reciprocating movement of the movable frame 6 can be used to switch the position of the laser emitter 3 under different operating conditions to compensate for temperature-induced detection deviations in the reading head. If the reading head's detection results are more demanding, a supporting plate 415 can be used to provide auxiliary fixation to the mounting frame 2.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
